SUPPLEMENTAL STOCK FOR SMALL-ARMS.

Specification of Letters Patent.

Patented Augf, 1918.

Application filed May 4i, 1918. Serial No. 232,497.

To all whom z'z may concern:

Be it known that I, WILLIAM C. Roenes, a citizen of the United States,residing at Fort Sheridan, in the State of Illinois, have invented Ynewand useful Improvements in Supplemental Stocks for Small-Arms, of whichthe following is a specification.

The invention has for its principal purpose the provision of asupplemental stock for small arms, such as pistols, revolvers and thelike, whereby such small arms may be converted into carbines.

The supplemental stock comprises an open frame designed for attachmentto the stock of the small arm, the frame being formed in two sectionswhich are hingedly or pivotally connected together, so that the framemay be broken substantially at the longitudinal center of the combinedunit, that is the framev and its attendant small arms unit, so that thedevice when not in use, may be folded up to require but a small amountof space. Carried by the frame, there is a rear sight, the support forwhich may be folded down against the frame or elevated to a position atright angles thereto, the support having associated with it a sleevemember designed to securely hold it in either of these two positions.The rear sight is ad justable vertically on the support to provide forits proper regulation with reference to the fore sight when it isdesired to shoot a prescribed distance.

The invention is illustrated and described in a specific embodiment, towhich, however, it is not to be restricted. r,The right is reserved tomake such changes or alterations as the actual reduction to practice maysuggest, in so far as such changes' or alterations are compatible withthe spir t of the subjoined claims.

The same numerals of reference designate the same parts throughout theseveral views of the drawing, wherein:

For the purpose of illustrating the invention, it is shown applied to asmall arm l of the automatic type and provided with the usual stock 2from which one of the wooden hand grips has been removed and replaced bya stamped metal hand grip 3 which is appropriately secured to the stock2. The supplemental stock comprising a part of the invention is attachedbetween this stamped metal hand grip Y 3 and the stock 2. Ylt is madepreferably of tubular material, and the ends which are secured to thehand grip are flattened as indicated at i and 5, so that appropriatescrews 6 may serve to attach the stock to the hand grip and secure itand the latter to the stock of the small arm l. Being made as shown, thesupplemental stock constitutes an open frame and comprises the sections7 and 8, the latter being appropriately formed at its eXtreme end forcomfortable engagement with the shoulder of the user. The section 8 isdesigned to be folded over against the section 7 and the arm to whichthe latter is attached, when the device as a whole is not in use and themeans permitting this folding over comprises a unique hinge connectionabout to be described. Since the supplemental stock is formed of tubularmaterial, the unique hinge members are contained within the same. lneach leg of the section 7 there is carri-ed a plug 9 which is rigidlyheld therein by a transversely disposed pin 10. The plug 9 projectsbeyond the end of the leg and in this projecting end carries a link 11which is rectangular in cross section and pivotally engages with a pin12 which is inserted section on the line 11-11 of Vplugs 9, the sleevemembers 16 thev ends Y remote from those Y movement.

. gaged from the pins 19 transversely through the plug 9 andfcrosses. arecess cut in the end of the latter and into which one end offthe link11 is inserted. Both legs of the section 7 are thus provided and the twolegs of thesection 8 engage the rear ends of these hinge members each ofwhich is' in the form of a -plug member 13 slidably held in the leg ofthe section 8. At one end the plug 13 is reduced in diameter thusproviding a shoulder 14E and at the extremity of this reduced portion atransversely disposed pin 15 is inserted, crossing a slot formed in theend of the plug and pivotally engaging the rear end of the link 11 whichenters the slot. Since the plugs 13 are movable longitudinally in thelegs of the .section 8, the latt-er may be moved longitudinally withrespectto the section 7, soV that the extreme ends of the legs of thesection 8 may be made to engage over the projectinor ends of the plugs9, and means is provided for retaining them in such an engagement. Thismeans comprise sleeve members 16` carried by the legs of the sectionY 8on Ywhich they are permitted a limited longitudinal movement and also alimited amount of angular movement, pins 17 being inserted in the legsof the sections 8 and projecting into and out of the latter, theoutwardly projecting portions Yentering rectangular shaped openings 18whose length describes the amount of longitudinal movement permitted thesleeves and, whose width describes the amount of angular movement.lVhenthe legs of the section 8 are made to engage the projecting ends ofthe to engage pins 19 carried by the legs of the section 7 and to thisend the sleeve members are formed with bayonet slots 20 at adjacentwhere the openings 18 are formed, the transverse portions of the bayonetslots being diagonally disposed, so that when the limited angularmovement is imparted tothe sleeve members 16V they may be moved slightlyin a longitudinal direction during such angular Obviously this is forthe purpose of having the `connecting legs of the` two sections of theYsupplemental stockA drawn tightly together. When the sleeve members 16are engaged with the pins 19, the two' sections of the supplementalstock. are secured together in extended position, butwhen the sleevemembers are disengaged' from the pins 19,V it is for the purpose ofVpermitting the section 8 of the stock to be Vfolded over' as shown indotted flines in Fig. 1. This is made possible because of the plugs13being slidable in the legs of the section 8. With the sleeve membersdisenthe section 8 maybe drawn away fromthe section 7, the legs of theformer section being disengaged from theprojecting ends of the plugs9,and the Ypleas 13 Vmounted and for are rdesigned l sliding towardtheends of the legs of the section 8 until the shoulders 14 abut theinwardlyV projecting ends of the pins 17. Thereupon the section 8 may befolded over as described, since the links 11 provide the necessaryhinged connections for this purpose. Y

On the upper leg of the section 7, there is carried a rear sight support21 which is made arcuate inv cross section and formed at one endwithears 22 upper leg of the section 7 and are carried thereby on thepins 23.* support is alinementwith its length and further provided witha tongue 25 at right angles to its length., ASince the sight support isdesigned for elevation to a right-angular position with reference to theattendant leg of the section 7 on which it is mounted, a slot 26 is theleg of the section 7 through pivotally sight support is elevated asdescribed.V In

elevated position the tongue 25 is brought against the leg of thesection 7 and in order that the sight support may be locked in thisYelevated position a ring member 27 is provided. This rounds the leg onwhich the sight support is a specified portion of its periphery isexpanded beyond the normal radiusy of the ring, thus providing' a camportion 28. sothat it simulates an S in cross section, so that there isprovided an outwardly projectingA bead or corrugation 29 and an inwardly projecting bead or corrugation '30 which are restricted only tothe cam por'- tion and exist in no other part of the ring. The tongue2dr-Vis recessed on its end face so as to leave aprojection 31 at itsextreme end while the tongue 25 is recessed on its upper aceto leave asimilar but oppositely disposed section- 32 -on its extreme end. V henthe sightsupport 21 is elevated, the tongue 25 lies against the legofthe section 7 on `top ofthe latter and the ringmember 2 may be movedVlongitudinally along the leg when the highest part of the cam portion 28may pass over the end of the tongue. Thereafter Van angular movementimparted tothe ring member 27 will cause the lower part of the camportion to be brought into contact with the upper 'edge ofthe tongue 25,and the projection 32 of the latter will be contacted with by the innerface ofjthe corrugation 29. YContinued angular movement imparted to thering member 28 will serve to eect a rm clamping operation of the tongue29 and the projection -32 will preclude thepossibility of anylongitudinal movement of the ring, so that the sight sup- The sightsupport 21 is which straddle theV rlhe sight'Y provided with a tongue247m This cam portion 28 is crimpedring memberloosely sursecured in thelower position in substantially the same way. When folded down againstthe leg of the section 7, its tongue 24: is brought to a position whereit may be engaged by the cam portion of the ring 27, but in thfsinstance the projection 31 of the tongue engages against the outer faceof the corrugation 30, thus securing the sight in lowered position andretaining the ring 27 in position in substantially the same way that itis retained when the sight support is in elevated position.

Adjacent the upper end the sight support is provided with a longitudinalslot 33 and the rear sight 34 is provided with a transversely disposedrib 35 which slidably engages in this slot, the sight support beingcounter-slotted on the front face so that there may be carried by thesupport a block member 35 provided with a screw stud 36 which projectsthrough a hole 37 formed in the rib 35 and in the sight and receivesagainst the rear face of the latter a lrnurled or milled nut 38. Thesight support 33 adjacent the longitudinal edges of the slot is suitablycalibrated to permit the intelligent adjustment of the sight relative tothe sight support for the obvious purpose of regulating the sight forthe shooting of various distances.

From the foregoing description and the accompanying drawings, it isbelieved that the construction and operation of the invention will beclearly apparent and further description is, therefore, omitted.

The invention having been described, what is claimed as new and usefulis 1. In a supplemental stock for nre-arms, an open tubular framecomprising two sections formed with interconnecting legs, plugs iXedlyheld in the legs of one section, other plugs loosely engaging in thelegs of the other section, connections between the plugs of the onesection and those of the other section, and means carried by the legs ofone section and engageable with the legs of the other section wherebythe two sections are rigidly connected together.
